W. D. GUSEMAN AND E. O. BRIGHT, OF MORGANTOWN, WEST VIRGINIA Letters Patent No. 97,392, dated November 30,1869.

IMPRQ'VED INBU'LA'IOR FOR TELEGRAPH- WIRES.

Thesehedulo referred to in these Letters Patent making part of the same.

To all whom it may concern y Be itknown that we, W. I). Gvsnmm and E. 0. BRIGHT, of Morgantown, in the county Monongalia, and State of West Virginia, have in'"! .d a new and usefirl Improvement in Telegraph- .re Insulators;

- and we dohereby. declare that the following is a full,

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the :wcompanying draw-- ings, forming part of this specification.

v This invention relates to anew and useful improvement in insulators for. tclegraph-wires,'and consists in the form of the wire-aperture through the insulator,

and the portion of the slotin the insulator, as hereinafter described.

In the accompanying drawing- 'Figure 1 represents a side view of the insulator,

partly in section.

Figure 2 is a top view.

Similar letters of reference indicate corresuonding parts.

A is the insulator, which, in its outline, does not differ materially from other insulators.

The aperture in which the wire B rests, passes directly through the insulator. The bottom of this hole, or wire-aperture, is grooved or sloped downward from the middle, or from any other point, so that water will run off. fromthe hole, and a ridge be left for the wire to rest on.

These grooves or slopes from the hole are tapering, as indicated in the drawing, while the wire rests on a narrow-ridge in the hole.

The telegraph-wire Bis introduced into the aper tom 0 through a slot, 1 which slot is placed at an angle with the direction of the wire-aperture, as seen in ii". 2.

v This slot 1) may he in the side of the insulator, instead of the apex. In either case it is placed at a suf- -fic-ien-t angle 'to secure. and fasten the wire in the aperture.

It will be seen that the insulator is a self-fastener for the wire, by this angularity of the slot 1).

The insulator may be made of glass, or any other suitable material.

Having thus described our invention,

\Ve claim as new, and desire to secure by Letters Patent I 1. The narrow ridge or point in the insulator, formed by the grooves, or a groove extending downward from the wire-aperture, on which ridge the wire rest-s, sub stantinlly as described.

2. The sloping grooves, (one or more in number) extending from t-liewire-apertm'e, for discharging the water and forming a ridge for the wire to rest on, substantially as described.

3. The insulator A, constructed with the aperture 0 and slot D, arranged at an angle with each other, as shown, either with or without a cap'to protect it from the weather.

- The above specification of my invention, dated this day of 1869.
